  • Patent number: 4483808
    Abstract: An elongated metallic conductor is insulated with an inner layer of a plasticized polyvinyl chloride composition and an outer layer of a plasticized, irradiation cross-linked polyvinyl chloride composition. The outer layer has a low coefficient of friction to facilitate pulling in central office racks, has mechanical properties which are required for installation and use and, in a preferred embodiment, has a thickness which is substantially less than that of the inner layer. The layers are extruded in the same extruder crosshead that seemingly causes the outer layer to bond to the inner layer to facilitate stripping of the composite insulation from the conductor.
    Type: Grant
    Filed: November 18, 1983
    Date of Patent: November 20, 1984
    Assignee: AT&T Technologies, Inc.
